What type of machinery and equipment do you have in your facility?

All the equipment and machinery included in the assessment should be identified and classified both by the contractor and the asset owner, according to:

  • Dismantling complexity: a value from 0-easiest to 10-high complexity
  • Classification: whether the equipment can be recovered and dismantled to reuse in another location, can be sold to another company, recycled, scrapped
  • Resale: a value determination can also be helpful to make decisions
  • Risks: potential dangers during the dismantling Also, the potential dangers that may come about if dismantling or demolition is delayed. (Deterioration)
  • Comments: any other remark or observation.

During this process of machinery inventory, asset owners should give contractors as much in- formation as possible, so demolition professionals can plan and develop the best solution with the most accurate cost.

What is the condition of the building / structure?

Appropriate assessments should include a building and structure survey. This study is aimed to analyse the current condition of the building structures and infrastructure, identify high risks to safety that should be addressed whenever they are considered unacceptable, and to verify and identify possible contamination within the structures. The main benefits of undertaking a comprehensive audit of this nature include optimising valuable resources, potentially reducing demolition costs, reducing waste-management costs, and developing a comprehensive and con- sidered end-of-life strategy.

The building assessment should include consideration of interior and exterior walls, floors, steel structures, concrete, timber, composite materials, hazardous materials, as well as to identify additional potential hazards:

  • Electricity systems
  • Underground water system
  • Unsound structures
  • Heavy mechanical objects
  • Pressurised pipelines
  • Gas and vapour
  • Chimneys

Foundations, landscaping, adjoining properties and structures also need to be considered, as do the existence of basements, right of way, boundary walls, accessibility to rail, road, water- ways, gas & electrical services, and any other encumbrances. If reuse or refurbishment is not feasible, the audit should include an estimate of the types, volumes, and intended treatment of waste materials likely to arise from the demolition.

Based on the measurements taken on-site or from detailed site drawings, the total volume of each element to be removed from the building should be calculated.

Once every building and structure has been correctly checked, we can prepare a template to control the execution of each phase of the project.

Any historical documentation or incident reports and registers are crucial during this survey; with consideration of events, accidents, or operations from the past that could have affected the condition of the structures. In the event that any major hazard is identified during this study, a secondary engineering survey should also be undertaken as an interim measure.
